We always stay there. It's been hit or miss for us. In September, the buses to DHS took FOREVER. If you just missed one, you wanted at least 30 minutes for the next one, which by that time, there was a long line and you had to practically shove your way on because people just walking up jumped the line and got on first and there was never enough room for everyone. The rest of the buses were good. In January (last year), no issues at all. We're going again in 2 weeks and staying there again. Hoping for an easy time again.
If you're staying at Jambo, you have to wait for the buses to go to Kidani first so there's always a chance they can be full when they get to you (except DTD, which is the opposite). A lot depends on when you're going with that.
All in all, we love the resort more than the bus problems so we continue to stay there and just leave earlier than we need to in order to get where we want to go.
